UNITED STATES rPATENT S. F. EMERSON, OF CANAAN, OHIO.

ATMOSPHERIC CHURN.

SpecificationV of Letters Patent No. 7,236, dated April 2, 1850.

To all whom t may concern:

Be it known that I, SIMEON F. EMERSON, of Canaan, in the county of Wayneand State of Ohio, have invented certain new and useful Improvements inAtmospheric Churns, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawing, whichforms part of this specification, and in which- Figure l is aperspective view of my churn complete, and Fig. 2 is a perspective Viewof the same with a portion of the tub removed to show its interiorconstruction.

My improvements consist in constructing the dasher in a peculiar mannerwhich unites simplicity with efficiency and in se curing inclined tubesto the sides of the churn tub which tubes not only assist the mechanicalaction of the dasher, but in addition feed down air into the milk orcream during its agitation.

In the drawing, A is the churn tub, which in this instance consists of asquare box` the cover of which is made in two pieces to allow oneportion to be removed to inspect the cream without disarranging thedasher.

The latter is constructed in the followingl manner: A squared sheet oftin plate or `other metal is slit from each of the corners toward thecenter of the sheet for rather more than half the distance from thecorner are united there thus forming a beater B, with four arms, whichis secured to an upright spindle a, which, passing through the center ofthe sheet, has its lower extremity stepped in the bottom of the churntub. The spindle passes upward through the cover of the churn tub andhas a spindle, b, 'secured to its upper extremity which is put 1n motionby a wheel, c, turned by a crank.

Inclned tubes, d, are secured to the sides of the churn tub; theseincline forward, as they descend, in the direction in which the dasheris revolved, and break the currents produced by the revolution of thedasher while at the same time they feed down air into the wave of creamor milk.

The several members of my machine may be constructed of such materialsas the manufacturer may deem best suited to accomplish the ends soughtin its invention, viz: efficiency, cheapness, and facility for cleaning.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the dasher with the stationary inclined air channelson the churn tub, the two being made, arranged, and operating,substantially as herein set forth.

Intestimcny-whereof I have hereto signed my name.
